a point arose about this is not poetry

[Leanne]

Some are attempts at poetry that haven't quite made it yet... it's not as simple as "it's a poem if I say it's a poem", because I'm afraid that someone else really does have to agree with you. A consensus of two might be enough to make it a poem, if not necessarily a good one. The more you read (and write), the easier it becomes to recognise when someone's doing something different on purpose and when they're just making an error out of ignorance.

Beginners mostly fall into the latter camp, but immersing themselves in poetry will make this happen less frequently.
